It's the centerpiece of a smarter, simplified home."
New Honeywell Home X8S Smart Thermostat Features
Backed by over a century of innovation, the Honeywell Home X8S smart thermostat is ideal for customers seeking a sleek, modern design and a smarter, energy-efficient solution. Its key benefits and features include:
- Convenient video doorbell streaming and intercom: With a first-of-its-kind video doorbell integration,2 homeowners can view live video streams from First Alert® or Ring® doorbells and speak to visitors directly from the thermostat.
- Intuitive customizable touchscreen: The sleek, five-inch touchscreen enables intuitive operation of temperature programming and customized idle screens that display information the homeowner wants to see, including a five-day weather forecast, digital clocks, indoor air quality (IAQ) information, design themes and color combinations to match any home décor.
- Awareness and control of IAQ: In addition to maintaining ideal temperature, the smart thermostat monitors humidity, tracks volatile organic compounds and estimates carbon dioxide levels. HVAC installers can help homeowners maintain optimal IAQ with humidity and ventilation control to keep the home's air fresh.3
- Proactive HVAC system performance alerts: The X8S smart thermostat continuously monitors the HVAC system, and a notification is sent to both the homeowner and their technician4 when an unusual pattern is detected – enabling a proactive service that helps prevent minor issues from escalating into costly system failures or unexpected loss of comfort.
- Intelligent energy savings: The thermostat's optional Smart Room Sensors help prioritize room comfort when at home, Adaptive Recovery technology learns how long the heating and cooling system takes to reach the programmed temperature, and auto-away technologies on the First Alert® app adjust the system automatically to deliver energy savings when away. Honeywell Home smart thermostat users save on average $204 annually when using its recommended scheduling feature consistently.5
